High pressure air system for airsoft gun

Abstract

A high pressure air cylinder to use in an airsoft gun or similar devices and systems. In some embodiments, the present general inventive concept encompasses a cylinder in which an imbalanced poppet valve directs and controls the axial motion of a piston. Some embodiments include a two-way solenoid valve. Some embodiments include a precisely sit two-way solenoid valve. The solenoid valve controls the flow of air to drive a piston forward; air then pushes the piston back into place.

What is claimed is: 
     
       1. A high pressure cylinder for use in a gun, comprising:
 a cylinder frame body; 
 a piston having a nozzle and a piston base portion, said piston defining a central air channel through the piston base portion and nozzle, said piston configured to move within said cylinder frame body along an axis, said piston base portion including a first piston head surface and a second piston head surface, said piston being configured to move between a forward position and a back position; 
 a solenoid valve configured to direct a fluid to said piston base portion such that fluid pressure on said first piston head surface moves said piston from the back position to the forward position; 
 an auxiliary fluid line configured to direct fluid against said second piston head surface such that fluid pressure on said second piston head surface moves said piston from the forward position to the back position; and 
 a baffle member interposed between said piston base portion and said cylinder frame body. 
 
     
     
       2. The high pressure cylinder for use in a gun of  claim 1  wherein said baffle member includes air slits configured to pass air from a secondary air line to said second piston head surface when said piston is in the forward position. 
     
     
       3. The high pressure cylinder for use in a gun of  claim 1  wherein said first piston head surface and said second piston head surface are opposing surfaces of one piston member. 
     
     
       4. A high pressure cylinder for use in a gun, comprising:
 a cylinder frame body; 
 a piston having a nozzle and a piston base portion, said piston moving within said cylinder frame body along an axis, said piston base portion including a first piston head surface and a second piston head surface, said piston configured to move between a forward position and a back position, and said piston defining an air channel entering said piston base portion and exiting through said nozzle; 
 a solenoid valve configured to direct a fluid to said piston base portion such that fluid pressure on said first piston head surface moves said piston from the back position to the forward position to open said air channel; and 
 an auxiliary fluid line configured to direct fluid against said second piston head surface such that fluid pressure on said second piston head surface moves said piston from the forward position to the back position to close said air channel; and 
 a baffle member interposed between said piston base portion and said cylinder frame body. 
 
     
     
       5. The high pressure cylinder of  claim 4 , wherein said air channel has a first opening in said first piston head surface, and a second opening in said nozzle. 
     
     
       6. The high pressure cylinder of  claim 5 , further comprising a central head member configured between said solenoid valve and said piston, wherein said first opening in said first piston head surface is configured to receive said central head member to close said air channel when said piston is proximate said back position. 
     
     
       7. The high pressure cylinder of  claim 6 , wherein said central head member is configured to close said air channel until said piston has moved a predetermined distance forward from said back position. 
     
     
       8. The high pressure cylinder of  claim 7 , wherein said piston is configured such that upon moving said predetermined distance forward from said back position, said first opening is not blocked by said central head member such that gas from said solenoid valve moves through said air channel. 
     
     
       9. The high pressure cylinder of  claim 4 , wherein fluid from the said solenoid valve is dispelled through said air channel when said piston moves proximate said forward position. 
     
     
       10. The high pressure cylinder of  claim 4 , wherein said baffle member includes air slits permitting passage of air from a secondary air line to said second piston head surface when said piston is in the forward position.
